Phase five

Los Alamos physicists have conclusively demonstrated the existence of a new phase of matter.

Phase five

Scientists still have more to learn about the exotic physics of specialty materials.

What makes the cuprates special? How about a new phase of matter.

Ceramic metals known as cuprates have mystified physicists for decades. They exhibit a variety of distinct phases of matter, each with its own specific properties, including a phase bearing an exotic type of magnetism, a high-temperature superconducting phase, an ordinary metal phase, a poorly understood and weird metallic phase simply called a strange metal, and an equally poorly understood metallic phase known as the pseudogap. The existence of this last pseudogap phase was recently confirmed in an clever experiment at Los Alamos, marking a potentially important milestone in materials science and high-temperature superconductivity.
